To al! @from it may concern.'

e il known that L Loris l. Dns'rmnnrs, risen of France, and resident of Trenion. in the county of Mercer and State of Yew Jersey. have invented a new and use ied improvement in Apparatus for Impregnating and Coating il'latcrials, of which the ollowing' is a specilicatitni.

lia iinpregxmting and coating materials, such as fabrics.. cords, cables and the like, in the ordinaryv manner, Where air is not, ex-

hausted 'troni the material, certain particles of air will remain in the material thus causing l ibbies to forni therein during the imriregnating and coating process, which bubbies. as they burst, expose non-impregnated or coated portions of the material to eX ternal atmosphere and thus materially impair the quality and usefulness of the niatrrial Vfor the purposes intended.

The object of this present invention is to obviato the above faults by providing means for in'ipregnating.and coating the material after the air has been exhausted therefrom and before the material comes in cont-act with tbc external atmosphere, the said Inaterial being preferably also thoroughly dried while the air is exhausted therefrom.

This invention consists broadly in an apparatus having a vacuum chamber and a liquid container tl'irough which the material passed from the. vacuum chamber before .rc-aching external atmosphere.

A practical embodiment of this invention is represented in the accompanying draW- ings.y in whichW l `igurc 'l represents un apparat-us adapted for treating a fabric, in top plan, Fig. 2 is a longitudinal vertical central section through the same, Fig, 3 is an end view, a portion of the door for the vacuum chamber being broken avvaj,r to inore clearly show the parts within the chamber. and Fig. 4. is a transsection toben/dfn the plane ot' the line /t--A of Fig.

The roll of fabric to be treated is denoted by 1 and its core 2 is provided with suitable trunnions 3 resting upon supports 4 uprising r` .=V 'wheeled trut-li' fi, the wheels of which aloi . web troni a rol use, is closed at both ends. In the present instance, the end 8 is shown permanently closed and the other end shown as provided with a door 9 hinged at 10 to the body por tion of the vessel 7. This door may bc provided with a packing 11 for sealing the door air-tight when closed., bolts 12 or other suitable fastening devices serving to lock the door in its closed position.

The truck bearing the Aroll of fabric may be moved into and out of the vessel 7 when the door 9 is opened by inserting a removable track section 6*, indicated in dotted lines, between the track sections 6 Within and without the vessel 7. This traclrsection 6* is removable to permit the opening and closing of 'the door 9. Ylhe interior of the vessel *7 may have the air exhausted therefrom in any suitable manner, asF for instance, byan air exhausting pump 13 of well known and approved form. An annular series rif-steam pipes 414- is pro erly supported within the vessel 7 aroun 'roll of fabric l, which steam pipes may be provided with the usual steam inlet. and outlet pipes 15, 16, extending through the end wall 8 of the vessel. A liquid container 17 is mounted upon the top ot the vessel-'7, which liquid container is provided with a slot: 18 in its bottoni, through which slot the fabric is led from Within the vessel 7 into the liquid container A17 for e1 agement with the liquid therein before t e fabric comes in Contact, with external atmosphere. Suitable-naps 19 may be provided in the bottoni of the container 17 for engaging the opposite sides of the fabric it. leaves the slot 18 for preventing the liquid within the container 17 f1 om being drawn into the interior of the vessel 7.

The fabric web as it leaves the liquid conable core 2O having trunnions 21 supported rby brackets on uprights 23. A suitable heater 24 is located between the tainer/l'l and the winding pose of drying the coated fabric. liquid container pair of rolls 25 roll foi' the purpud impregnated and 'l`lie ,ric as it leaves the 17 may also pass through a arranged to lend the fabric iocated within the. vessel 7 straight through the slot-.18 in the bottoni of the. liquid .container 17. To thor-on hiv dry the fabric within the vessel 7 the fa rib theY liquid con-I tainer 17 may be Wound into a roll on a suit I rolt 'is passed around the illu i illy extended branches oi' the u pipe within the vessel before beinon letl [l the roll 2G and upwardly through the the Container :il

, f n .from the above dee a-iption by inserting the roll of Afabric to be into the v 'sel T anti then exhauat- 1ir from the Said reeeptaele, that the exhaust (t 'from the fabric. )it the time the fabric irs'a`leo thoroughly cirietl L i hereinabove deseribeti or t er Suitable drying apparatuis. rie i5 then letl through the liquid 'iu the container l? thus permitting the liquitl to thoroughly imp'regjnate the fabric as well t the opposite rtl .es thereof beferethe Contea into Contact witl` external atsere. This insures; the complete nn- U ation and treating ot the fabric anti awoiuteiy preferite 'the formation oi air bubbles; therein.
